SPECIFIGATION `raming part of Letter Application filed September 23, 1882. (No model.)

' connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot thesame,

and which said drawings constitute part ot' this specification, and represent, in

Figure 1, a sidev view; Fig. 2, a vertical eentral section; Fig. 3, a perspective view of the lever detached.

This invention relates to an improvement in -that class of tireextinguishers which consist of a nozzle arranged at different positions in an apartment, and whereby when a re occurs in that apartment the heat generated therefrom liberates the valve which-holds back the iiow of water, and permits the water to escape and be distributed by the apparatus itself' over a large space within that apartment.

Various devices for the distribution of water in the apartment havebeen devised; but in practice it is found that a distributer which will start the water in a thin sheet, so-that it will soon break into spray, is the most successful; but with this class of distributers a diiiieulty has been experienced in sealing the Ywater-way by means ofa device held by solder or other fusible material without the employment of serewsor other means of adjusting or forcing the valve upon its seat.

'lhe object of my invention is to overcome the difficulties existing in this class o'f distributers; and it consists in the construction as Y hereinafter deseribed, and particularly recited in the claim.

A represents the nozzle, which is attached to the pipe in the'usual manner of'attaching distributers. On opposite sides, near the outer end of the nozzle, arms B extend to the right and left, and to these arms two legs, C, ot' a i'rameare attached. This trame extends forward ot' the nozzle,and in a cross-bar, D, carries the spindle E of the valve or distributer F, which works loosely through the bar, and so as to be moved freely in axial line toward or from the mouth of the nozzle, as the case may be. The distributer yF is cup-shaped, opening toward the nozzle, and carrying upon its inside any suitableelastic material, G, but

less in thickness than the depth of the cup..

Outside the crossbarjD the frame extends, having two arms, H I, In one ot' these a not-oh, a,'is made.

L is a lever, slightly forked at one end, as v at b, Fig. 3, and so as to engage the arm H underthe notch a, as seen in Fig.2. The other end of the lever Lis forked, as at d, Fig. 3, so as to pass down over the arm I, one leg of the fork each side the armI, but so as not to makea tight fit. Theunder side oftheleverL is camshaped, or projects downward,as at c, and so as to enter a notch in the end of the spindle E, or to bear firmly on the enda'nd serve as a means for applying the power of the lever to the spinrile. When the valve has been set upon the mouth ot' the nozzle the end b ot' the lever is introduced beneath the notch a in the arm .H, the lower side of the lever brought to bear upon the spindle, and the forked end pressed Vhard down until a sufficient force be applied to hold the valve against the pressure of the water, and in that position the end d of the lever L is soldered to the arm L In thus applying the power of the lever the spring G is pressed upon the mouth of the nozzle, so as to make a water-tightjoint. When a tire occurs and sufficient heat be generated to melt the sol der the arm L is released, taking from the valve the power which held it against the force ot' the water. The valve thus liberated iiies'outward, guided by the spindle E, until the back ot' the valve strikes the bar D and is there arrested. In that 'position the cup serves as a distributer, into which the stream of water will strike and. be deflectedoutward over the edge of the cup in all directions. In this construction it is impossible for any water which escapes from the nozzle to reach the solder until after the liberation of the valve shall have been complete. VHenee'such flow of water cannot possibly check or interrupt the action of the heat upon the solder.

I am aware that cup-shaped distributers have been arranged in front of` a nozzle, and

`also that distributers have been made mov-V able from a position close upon the nozzle to IOO t position in front, there to serve as a disfulernm for one end of the lever, and the lever tributer, and therefore do not claim broadly arranged to bear' forcibly upon the spindle of sueh construction; but the valve, and secured to an extension of the What I do claim isframe upon the opposite side to the .fulcrum, 5 The combination of the nozzle A, carrying substantially as described. f arms B, and the frame C C D, with the eupshaped valve F, the spring or elastic material ALBERT M' BURRI El' G therein, the said valve provided with a spin- Witnesses: die Working freely through the arm D, and the JOHN E.
